Ibsen Phase masks – List of Technical and Application Notes
Recommended procedure for regular Phase mask cleaning.
This Application Note explains how different polarizations affect the fringe visibility of the interference pattern, and describes the methods used to calculate the fringe visibility, given 3 specific polarizations (TE, TM, and unpolarized).
This technical note derives the relationship between Phase mask period and Illumination wavelength that must be fulfilled for the 0/-1 order principle to work.
